VectorGap is the first Generative Engine Optimization (GEO) platform. It monitors how AI assistants -- ChatGPT, Claude, Gemini, Perplexity -- perceive, describe, and recommend brands in real-time. Traditional SEO tracks Google rankings. VectorGap tracks AI rankings -- a completely new visibility layer that most companies are blind to. We audited 150 SaaS brands and found that even companies ranking #1 on Google are invisible in 60%+ of AI-generated recommendations. Key capabilities include AI Perception Monitoring (real-time tracking of how every major LLM describes your brand), Hallucination Detection (instant alerts when AI spreads inaccurate information about your company), Share of Model Analytics (measure your brand's AI visibility vs competitors across all models), GEO Score and Optimization (proprietary scoring with actionable recommendations), and Competitive Intelligence (side-by-side AI perception comparison). VectorGap covers ChatGPT (GPT-4), Claude (Anthropic), Gemini (Google), and Perplexity in a single dashboard. A free AI Perception Checker is available at vectorgap.ai/tools/ai-perception-checker. Built for marketing leaders, SEO teams, and brand managers at SaaS companies who need to control their narrative in AI-powered discovery.
